I'm just in the midst of buying a used Yanmar 3GM30 engine (I got a deal .
The mechanic I hired to check it out pointed out that the oil pan has NO
drain plug! He did mention that he had drilled and tapped a few Yanmar's
oil pans for a drain fitting to drain it out.

Do you know of anybody else that has done this - I suspect that the oil pan
may have a thicker spot / dummy plug for just this operation?

Yanmars don't have them. In our installation, we couldn't get a pan
underneath to use it, anyway. We were warned off of putting a plug or
drain tube in the pan: possible leak point. I'd rather spend a few
minutes pumping from the top than have the oil drip out of a makeshift
drain while I wasn't looking.

We have a little bronze hand pump with a tube that fits in the dipstick
hole and a plastic tube into the waste container. Came with the boat so
I don't know the manufacturer. Does the job for us in about 10 minutes
and fits into next to no space.

I've used all the vacuum thingies and I find Jere's simple brass pump
is the best. Mine is permenently mounted in the engine compartment
with the hoses coiled and resting on a oil absorbent pad under the
engine. I use a 16" length of brake tubing as the dipstick insert. No
muss, no fuss, A dirty job tamed.

Topsider pump works well but the oil must be hot to flow.
My drain pan plugs have never been out of the engines.

Hi,

What's the best thing for the money for removing oil
from a motor in the bilge? I bought a drill pump, and
it worked okay. Once! After that it would never work
again. Someone told me about using a basting squeeze
bulb, and that worked great getting some lube out of
a transfer case, but it took quite a while and a lot of
times filling and emptying it. It would take forever to
empty a motor of oil, unless there's a quart size or
something.

Thanks for any suggestions,
David
